As you may be aware, new PCI DSS requirements state that all payment systems must disable early TLS by 2018.


In preparation for this requirement, Authorize.Net plans to disable TLS 1.0 and TLS 1.1 on the following dates:


  • Sandbox -- April 30, 2017
  • Production – February 28, 2018

We are disabling the sandbox in advance of production to allow you to time to test your solution and ensure you are no longer using TLS 1.0 or 1.1.


Please check the code for your solutions and systems to confirm that they can default to TLS 1.2 for your API connections.


You can review our API Best Practices for details about TLS 1.2 platform support, cipher recommendations, and other integration suggestions:
